MLED installation script as a proof-of-concept

Rather strange error. It seems to indicate that slackpkg package was not installed. Can you check if this package has been installed by running (as root at least for the second command):

Code:

$ ls -l /var/log/packages/slackpkg*

and

Code:

$ which slackpkg

and then check the PATH variable of root user:

Code:

$ set | grep PATH

I might have a corrupt install. I'm about to format and reinstall. Will report back in a couple hours.

Indeed, there is no slackpkg package installed and two slackpkg+ packages installed according to this log.

For your information, if slackpkg is installed, you'll get the following:

Code:

$ which slackpkg
/usr/sbin/slackpkg

Just did a clean install, everything is running smooth again. Sorry for the misunderstanding. I will report any new findings. Thanks for a wonderful script.

gegechris99 · 04-08-2016, 03:23 PM

Another update of script mledauto.sh.

Main changes:
- Improved behavior of the script after a restart: deletion of directory "microlinux" before git, use upgradepkg instead of installpkg to (re)install slackpkg+ package
- Selection of the mirror transfer protocol (http or ftp) before displaying the list of mirrors from the online mirror list
- Added bear.alienbase.nl to the list of suggested mirrors
- Various code cleaning (mainly for echo command)

Unitary tests were OK.

Code:

Hello,

I made some code cleaning and some small optimization in both the mledauto.sh and mledconfig.sh scripts. No new features in these updates.

I made a small change of behavior in mledauto.sh. The script will no longer delete the slackpkg+ package and microlinux git repository when the installation is completed. Instead, it will delete any existing slackpkg+ package and microlinux git repository before downloading and installing them. So relaunching the script after an error (ex: breakdown in internet connection) should go smoothly, no more complaint about existing file/directory at least during my unitary tests

For the curious, I provide the diff between these updates and their previous versions.

mledauto.sh

Code:

$ diff mledauto.sh.txt.old mledauto.sh.txt

Herewith an update of script mledconfig.sh that comes with a new feature: "Select keyboard for Xorg".

Unitary tests are OK here.

At this point, mledauto.sh and mledconfig.sh cover most of the steps described in the MLED installation guide.
What is left out from the scripts:
- Installation of Slackware (for obvious reason)
- Switching to generic kernel
- Install VirtualBox Guest Additions
- X11 in a nutshell except for keyboard configuration
- Basic maintenance (not applicable to installation scripts)

For now, I do not intend to add new features to the scripts and will only update the scripts based on feedbacks (bug report, advice on code cleaning...) or after my own code cleaning (these scripts are a good opportunity to improve my scripting skills).

Code:

What about this?

Code:

# /etc/inittab
...
# Default runlevel. (Do not set to 0 or 6)
id:4:initdefault:
...

I also believe having the Generic Kernel as an option may be a good idea.

Have something like

Would you like to switch to Generic Kernel? [Y|N]

Users having the option wouldn't hurt the system at all. I can afford some format and clean installs. I'm still building my app database for Slackware. I do a lot of networking, so I am testing apps I like. You have done a great deal and if this is where you get off, its still gratitude. Thanks for making my Slack experience a breeze. Enjoy.

gegechris99 · 04-18-2016, 12:27 AM

Thanks for the suggestions:

/etc/inittab: no problem, I will add the change to level 4 at the end of mledauto.sh. It's quite easy to do.

Switch to generic kernel: I have a logic in mind to provide such an option using the great mkinitrd_command_generator.sh script. If you're willing to test it (and from you post I assume you are), I will try to provide an option in mledconfig.sh.

PROBLEMCHYLD · 04-18-2016, 06:49 AM

Thank you very much. My test machine is ready.

gegechris99 · 04-18-2016, 03:19 PM

Herewith the requested update of mledauto.sh and mledconfig.sh.

mledauto.sh changelog:
- Added a step at end of the script to switch to runlevel 4 in /etc/inittab

Unitary tests are OK.

mledconfig.sh changelog:
- Added option "Use generic kernel". This option will automatically switch to the generic kernel installed on the system instead of the currently running kernel.

The option will disable the boot menu so that the system will boot directly with the generic kernel. As such, it is not advised to use this option if you have a multi-boot system (ex: Slackware + Windows).
The option was devised to not mess up lilo.conf if it is run multiple times (each time, the previous version of lilo.conf is saved as lilo.conf.orig). For example, if you run it twice in a row, lilo.conf will not change. You can check this by comparing /etc/lilo.conf and /etc/lilo.conf.orig

This option could also be used after a kernel upgrade to install the upgraded generic kernel. However I didn't test this use case. But it explains why I named it "Use generic kernel" instead of "Switch to generic kernel". Any advise on a proper naming of the option is welcome.

I tested this new option on my main machine and it worked

This is the error, and the Kernel didn't switch to Generic.

Can you post the content of both files: /etc/lilo.conf and /etc/lilo.conf.orig?

You can use the cat command:

Code:

cat /etc/lilo.conf
